Rock Type: mineral

Physical Properties
Hardness: 7 (Mohs scale); Color: Banded purple, lavender, and white; Luster: Vitreous (glassy); Crystal Structure: Hexagonal/Trigonal; Cleavage: None; Specific Gravity: 2.65
Formation & Geological History
Formed in hydrothermal veins or cavities (geodes) where alternating layers of amethyst and milky quartz grow over time. Often found in volcanic rocks (basalt). Geological age varies by deposit, typically Mesozoic to Cenozoic.
Uses & Applications
Primarily used for lapidary work, jewelry (beads, cabochons), metaphysical balancing, and ornamental/collector specimens.
Geological Facts
Also known as Dream Amethyst or Banded Amethyst, the 'Chevron' pattern refers to the V-shaped bands of quartz. It combines the strengthening properties of quartz with the stress-relieving properties of amethyst.
Field Identification & Locations
Identified by distinct V-shaped or 'zig-zag' banding of purple and white. Found commonly in Brazil, Uruguay, Namibia, and India. Collectors should look for sharp color contrast and high transparency in the purple sections.
